Unified end user notification platform

ABSTRACT

A unified end-user notification platform delivers event alerts to different types of clients including mobile devices and HTTP clients. Users can subscribe to a plurality of notification channels and select from the associated various delivery options via a single user interface. The events are received by the unified notification platform which matches the received events with the user subscription data to identify subscribers and their respective delivery options. Corresponding event alerts are generated and delivered based on the user or subscriber specified options. Multiple event alerts corresponding to public and private data notification channels are provided to a user device via a single connection.

BACKGROUND

The advances in wireless Internet technologies and mobile computing lead to the booming of many services that serve data such as stock alerts, weather updates or personal communications including emails or instant messages to the millions of users via various devices. User preferences can be collected and the data can be served based on each user's individual preferences. The data for different categories can be formatted differently and may be delivered to the user via different applications executing on the user device. While HTTP clients display data via a browser, mobile devices such as smartphones can employ native “Apps” that execute on the operating systems such as iOS, Android or Windows Phone to display the data to the users.

SUMMARY

This disclosure relates to systems and methods for providing a unified end-user notification platform capable of delivering different types of information associated with public and/or private notification services to each of the millions of users based on each user's individual preferences. A processor-implemented method for providing the notifications is disclosed in accordance with one embodiment. The method comprises, providing a user interface that enables a user subscription to at least one notification channel providing public data and at least one notification channel providing private data and receiving user selected options for receipt of event alerts or messages from the notification channels.

Likewise, a reasonably broad scope for claimed or covered subject matter is intended. Among other things, for example, subject matter may be embodied as methods, devices, components, or systems. Accordingly, embodiments may, for example, take the form of hardware, software, firmware or any combination thereof (other than software per se). The following detailed description is, therefore, not intended to be taken in a limiting sense.

In the accompanying drawings, some features may be exaggerated to show details of particular components (and any size, material and similar details shown in the figures are intended to be illustrative and not restrictive). Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the disclosed embodiments.

The present invention is described below with reference to block diagrams and operational illustrations of methods and devices to select and present media related to a specific topic. It is understood that each block of the block diagrams or operational illustrations, and combinations of blocks in the block diagrams or operational illustrations, can be implemented by means of analog or digital hardware and computer program instructions. These computer program instructions or logic can be provided to a processor of a general purpose computer, special purpose computer, ASIC, or other programmable data processing apparatus, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, implements the functions/acts specified in the block diagrams or operational block or blocks.

In some alternate implementations, the functions/acts noted in the blocks can occur out of the order noted in the operational illustrations. For example, two blocks shown in succession can in fact be executed substantially concurrently or the blocks can sometimes be executed in the reverse order, depending upon the functionality/acts involved. Furthermore, the embodiments of methods presented and described as flowcharts in this disclosure are provided by way of example in order to provide a more complete understanding of the technology. The disclosed methods are not limited to the operations and logical flow presented herein. Alternative embodiments are contemplated in which the order of the various operations is altered and in which sub-operations described as being part of a larger operation are performed independently.

For the purposes of this disclosure the term “server” should be understood to refer to a service point which provides processing, database, and communication facilities. By way of example, and not limitation, the term “server” can refer to a single, physical processor with associated communications and data storage and database facilities, or it can refer to a networked or clustered complex of processors and associated network and storage devices, as well as operating software and one or more database systems and applications software which support the services provided by the server.

For the purposes of this disclosure a “network” should be understood to refer to a network that may couple devices so that communications may be exchanged, such as between a server and a client device or other types of devices, including between wireless devices coupled via a wireless network, for example. A network may also include mass storage, such as network attached storage (NAS), a storage area network (SAN), or other forms of computer or machine readable media, for example. A network may include the Internet, one or more local area networks (LANs), one or more wide area networks (WANs), wire-line type connections, wireless type connections, cellular or any combination thereof. Likewise, sub-networks, which may employ differing architectures or may be compliant or compatible with differing protocols, may interoperate within a larger network. Various types of devices may, for example, be made available to provide an interoperable capability for differing architectures or protocols. As one illustrative example, a router may provide a link between otherwise separate and independent LANs.

A communication link may include, for example, analog telephone lines, such as a twisted wire pair, a coaxial cable, full or fractional digital lines including T1, T2, T3, or T4 type lines, Integrated Services Digital Networks (ISDNs), Digital Subscriber Lines (DSLs), wireless links including satellite links, or other communication links, such as may be known to those skilled in the art. Furthermore, a computing device or other related electronic devices may be remotely coupled to a network, such as via a telephone line or link, for example.

A computing device may be capable of sending or receiving signals, such as via a wired or wireless network, or may be capable of processing or storing signals, such as in memory as physical memory states, and may, therefore, operate as a server. Thus, devices capable of operating as a server may include, as examples, dedicated rack-mounted servers, desktop computers, laptop computers, set top boxes, integrated devices combining various features, such as two or more features of the foregoing devices, or the like. Servers may vary widely in configuration or capabilities, but generally a server may include one or more central processing units and memory. A server may also include one or more mass storage devices, one or more power supplies, one or more wired or wireless network interfaces, one or more input/output interfaces, or one or more operating systems, such as Windows Server, Mac OS X, Unix, Linux, FreeBSD, or the like.

Throughout the specification and claims, terms may have nuanced meanings suggested or implied in context beyond an explicitly stated meaning. Likewise, the phrase “in one embodiment” as used herein does not necessarily refer to the same embodiment and the phrase “in another embodiment” as used herein does not necessarily refer to a different embodiment. It is intended, for example, that claimed subject matter include combinations of example embodiments in whole or in part. In general, terminology may be understood at least in part from usage in context. For example, terms, such as “and”, “or”, or “and/or,” as used herein may include a variety of meanings that may depend at least in part upon the context in which such terms are used. Typically, “or” if used to associate a list, such as A, B or C, is intended to mean A, B, and C, here used in the inclusive sense, as well as A, B or C, here used in the exclusive sense. In addition, the term “one or more” as used herein, depending at least in part upon context, may be used to describe any feature, structure, or characteristic in a singular sense or may be used to describe combinations of features, structures or characteristics in a plural sense. Similarly, terms, such as “a,” “an,” or “the,” again, may be understood to convey a singular usage or to convey a plural usage, depending at least in part upon context. In addition, the term “based on” may be understood as not necessarily intended to convey an exclusive set of factors and may, instead, allow for existence of additional factors not necessarily expressly described, again, depending at least in part on context.

Various applications currently exist that provide information and entertainment to users through different communication networks including the Internet, cables or cellular networks. For example, various point solutions exist for disseminating public data via mobile apps such as for newspapers providing breaking news, financial data, weather updates. Alert channels can also provide such public data via emails or instant messages. Similarly, various modalities/devices exist for conveying private information such as emails, instant messages or SMS communications. Each of these channels can have a special user interface (UI) for users to specify their subscription interests and implements match through a set of ad-hoc SQL (Structured Query Language) tables and statements. Data for these different applications can be configured according to standardized or proprietary formats. In addition, different data retrieval procedures can be implemented by the different systems. For example, data that is changing within short time periods is retrieved by client devices via periodically polling the server. Stock prices or live scores associated with sporting events such as basketball or soccer games may remain constant for a given time period or can change unpredictably from one minute to another. Tracking such data to keep the user updated with the latest news necessitates constant, periodic polling of the server by the client devices even at times when the data remains unchanged. This results in wastage of resources for the users operating within the limitations of their fixed data plans and limited device power resources that are drained by the various applications that maintain many connections with multiple data sources to poll the servers and provide notifications/messages to the user.

The embodiments described herein provide for a unified notification platform that pushes different types of data to users via their preferred client/user device(s) without solicitation or even in absence of requests for data from the client devices so that usage of the devices' data and power resources are optimized. FIG. 1 illustrates a unified notification module 100 that provides information from various channels 140 to users in accordance with embodiments described herein. The users can employ different user devices 110, 112, 114 to receive alerts from different channels. The user devices 110, 112, 114 can comprise by the way of illustration and not limitation, HTTP clients, mobile and non-mobile applications. In an embodiment, a user registers with the subscription module 102 in order to receive updates or alerts from the various channels. During the registration process, the user can provide subscription information 152 such as but not limited to, the details of the channels from which the user desires to receive updates/alerts, the entities associated with alerts from the channels where applicable, one or more devices and modalities via which the alerts are to be received, frequency of alerts and other information necessary to deliver information to the user. The unified notification module 100 is configured to provide alerts from various channels 140 that include channels providing public and private data. In an embodiment the channels that provide public information can comprise those with structured data such as but not limited to, weather updates, sports and financial news like stock quotes, updates for applications running on the various devices or those channels with unstructured data such as breaking news. In an embodiment, the channels providing private data can include channels that provide personalized information and which require user authorization/authentication prior to providing information access. The unified notification module 100 also provides alerts from such channels that disseminate private information such as but not limited to emails, instant messages (IMs), short messaging channels (SMS). Particular ones of the various channels 140 can be selected by the user for receipt of alerts. In addition, the unified notification module 100 can also be configured to enable a variety of service criteria based on the requirements associated with each of the services 140. For example, for an IM (Instant Messaging) service, a quality specification of delivering each message exactly once can be implemented whereas for sports scores, a best effort delivery specification can be implemented. In an embodiment, the channels can register with the unified notification module 100 in order to provide events/updates to its registered users. Accordingly, when a new channel registers, a new channel and its associated metadata can be created to receive events emitted by the new channel and providing the corresponding alerts to subscribers of the new service/channel.

In an embodiment, the subscription module 102 can present a user with a unified user interface (not shown) at the time of registration. The user interface allows user registration for receiving event alerts associated with one or more of the various channels 140. When the user selects one of the channels 140, the user interface can be configured to present choices associated with the selected channel to the user. The user's subscription information 152 including the user's selections of the various channels 140 and related options are received and saved to the data store 120 by the subscription module 102.

In an embodiment, the specifications 154 for new alerts to be generated are based on the users' subscription information 152 saved to the data store 120. The alerts module 104 collects public and private events generated by each of the various channels 140, configures event alerts based on the subscription information 152. In an embodiment, each of the channels 140 can be configured to transmit events they generate to the alerts module 104 via associated channels which therefore function as destinations and/or source of events. In an embodiment, each of the channels can be identified by a name formatted as a path component of a URI (Universal Resource Identifier) without parameters. Channels can not only transmit public information wherein all subscribers receive alerts published by the unified notification module 100 on such channels, channels to communicate private information to a particular client can also be created. In an embodiment, when a new channel is initiated or a new subscriber registers with the unified notification module 100 a channel can be registered/created, for example, by the delivery module 106. Creation of a channel includes determining the metadata or attributes for the channel. The channel attributes can comprise a retention policy that determines the number of messages if any that can be retained. The attributes include an expiration policy including the time period after which the retrieved alerts expire and are no longer transmitted to the subscribers, a delivery policy comprising the number of retries, minimum and maximum delays for a target, number of maximum delay retries, throttle policy such as maximum receives per second and authorization model if any is required.

In an embodiment, the alerts module 104 can be configured to request the channels 140 for new events for generating alerts to the users. Event alerts for the users of the unified notification module 100 are configured via applying templates to the received events to generate the alerts. In an embodiment, the templates applied to generate the alerts can depend on the data format associated with the event, security restrictions and end points receiving the alerts. An event alert 154 thus generated is communicated to the delivery module 106 for transmission to the various user devices 110, 112 and 114. It may be appreciated that only one alert 154 is shown by the way of illustration and that at any given time millions of alerts may need to be generated for the various events generated by the channels 140 and received by the unified notification module 100.

The delivery module 106 receives the event alert 154 from the alerts module 104 and pushes it via various modalities based on the user subscription information 152 from the data store 120. In an embodiment, the delivery module 106 identifies the users whose subscription information 152 indicates that they are interested in the generated event alert 154. Thus, the delivery module 106 does not wait for one of the user devices 110, 112 and 114 to make contact/initiate communication or request data. Rather, the delivery module 106 pushes the event alert 154 to selected ones of the user devices 110, 112 or 114 even in the absence of a request message. In an embodiment, one of the user devices 112, 114 or 116 can thus connect to the unified notification module 100 without any specification regarding a resource. However, information from the events is still transmitted to the users via the long-live network connections that the user devices 110, 112 and 114 can maintain with the unified notification platform 100. In an embodiment, each of the user devices 110, 112 or 114 maintain a single HTTP or TCP connection with a server executing the unified notification module 100 to receive the multiple event alerts. For example, a single persistent connection can be maintained via long polling with a HTTP client by the unified notification module 100. This reduces the power expended by the user devices 110, 112, 114 to receive the alerts when compared to making a plurality of connections to receive the various types of event alerts.

In an embodiment, the generated event alert 154 can relate to public data such as alerts regarding a stock reaching a certain value which alert may have subscriptions from a thousand to about a million users. In an embodiment, the generated event alert 154 can relate to private data such as an instant message intended for a single user. When event alerts related to private data such as instant messages, emails or SMS (Short Messaging Service) messages are generated, the delivery module 106 implements the various authentication/authorization procedures to ensure that the private data is forwarded to the intended recipients at an appropriate end point such as an email application or an SMS interface.

In an embodiment, the end point to receive the alert 154 can be selected by a user or it can be determined by the unified notification module 100 based on, for example, the type of data and/or the user's presence information. The delivery module 106 can therefore, configure multiple messages related to one alert 154 based on the various receiving end points. Alternately, a plurality of messages in various formats conveying information from one event alert 154 can be configured by the delivery module 106. For example, information regarding a score update related to a sporting event from one of the channels 140 providing sports information can be conveyed to subscribing users via SMS messages, IMs, emails, or even a proprietary user interface associated with the sports information channel. In another example, if it is determined that an IM cannot be delivered via a user selected end point such as a proprietary app associated with the IM, the unified notification module 100 can be configured to deliver the IM to the user within a web browser and/or other mobile ‘apps’. The generated event alerts can be associated with both public data for which no authentication is needed and private data which requires authentication. Furthermore, a single user can receive multiple event alerts related to different data types at one or more end points.

FIG. 2 is a schematic diagram of a unified user interface 254 that facilitates alerts creation and management by the users of the unified notification module 100. It may be appreciated that the user interface 254 is shown only by the way of illustration and that other user interfaces can be employed with the unified notification module 100 to display available alert channels, collect user information and enable event alert management. The user interface 254 is presented to the user in response to the user request for registration. It comprises a channel listing section 302 wherein various alert generation channels are listed for user selection. Channels providing information regarding breaking news, daily news, Fantasy sports, stocks, travel destinations, weather watch or blogs can be selected by the user. Section 304 shows the channels selected by the user. For example, section 304 shows that the user selected to receive event alerts regarding three stocks and one travel destination. Section 306 shows the user interface that is presented when the user selects stocks watch channel for receiving alerts. It shows the various criteria such as the stock symbol, price rise or fall in terms of absolute prices or percentages for generating alerts. Section 308 shows the various modalities such as email, IM, or a SMS to a mobile device via which a user can choose to receive event alerts. In addition, the keyword news channel is selected which causes the presentation of section 310 that includes criteria for forwarding news items associated with “Include” keywords or filtering away the event alerts associated with “Do not include” keywords. Section 310 shows the frequency of delivering the event alerts. For example, the user selects to receive the keyword news alerts on a daily basis. A unified notification platform as discussed herein further facilitates centralized alerts management so that all alerts associated with a multitude of channels 140 may be turned on or off with a single user input 312 thereby mitigating the need for users to separately activate/deactivate each of the channels 140.

FIG. 3 is a block diagram showing the internal modules of the subscription module 102 in accordance with one embodiment. In an embodiment, the subscription module 102 further comprises a request receiving module 202, a selection module 204 and a user data recording module 206. When a user request for registration 252 with the unified notification module 100 is received by the request receiving module 202, the user interface module 204 provides a unified user interface 256 to the user to facilitate the user to register to receive notifications or event alerts from the plurality of channels 140 which comprise services providing public data and private communications. The unified notification module 100 provides access to different services having a variety of service quality specifications associated therewith. In an embodiment, channels 140 providing private data addressed to particular users such as emails or instant messages can cause the unified notification module 100 to implement separate authentication or authorization protocols in order to verify user identity prior to forwarding alerts.

When the user selects a channel, options associated with the selected channel are presented via a unified user interface 254 by the selection module 204. For example, if the user selects a financial information service, options such as but not limited to, the financial entities related to which the user desires updates, the events associated with the entities that are of user interest, frequency of updates, modalities for delivering the events and other options can be presented for the user's selection. The user selected options are recorded with other user information as subscription information 152 in the data store 120 and is used for producing specifications 256 for the alerts to be generated by the alerts module 104.

In an embodiment, a user's selections and associated criteria can be stored as an alert specification alternately referred to as alert spec., within the data store 120 and used for generating messages to the user. By the way of illustration and not limitation, if a user selects to receive an alert for an event where the stock price of YAHOO! exceeds $20.00, an alert specification for a query “select price from quotes where symbol=“YHOO” and price>=20” can be generated as stored as “channel/quotes/yahoo 20+”. When an event that matches the alert spec is received, it is automatically forwarded to the users who have subscribed to the channel ‘quotes’ and whose criteria to receive the message match that of the alert spec.

FIG. 4 shows a schematic diagram of the alerts module 104 in accordance with one embodiment. The alerts module 104 receives events 452 generated by the various channels 140 and configures alerts 454 in accordance with specifications associated with respective channels. Each of the channels 140 can have different service quality requirements. Based on the channel characteristics, the delivery module 106 can deliver the alerts as best effort or guaranteed service. By the way of illustration and not limitation, there can be upgrades associated with about ten or twenty application (channels) to be sent to approximately a million subscribers who may have registered to receive at least a subset of the events associated with the application upgrades. Accordingly, each user device can have multiple channels as each user may have registered to receive multiple ones of the available application upgrades. Thus, the alerts generation module 104 is configured to generate about a million alerts corresponding to the channels and subscribers who registered to receive the upgrades associated with such channels. Similar criteria can exist with respect to stock/sports notification channels. For example, there are hundreds of publicly listed stocks and games being played so the associated channels may have hundreds of channels. Each of the channels serves alerts associated with a respective stock/game on best-effort basis to subscriber population ranging from a few thousand to millions of registered users. Other channels providing individual events such as chat, mail counter, messenger may have channels based on the number of alerts to be provided by the channels since the alerts are addressed to individuals and accordingly can require authorization prior to delivery. The alerts module 104 is thus configured to produce alerts for events from the multitude of channels providing public or private data and wherein each channel may have unique requirements.

The events receiving module 402 receives events from the various channels 140. In an embodiment, the events can be pushed by the channels to the events receiving module 402. In an embodiment, the events receiving module 402 can poll the channels at regular intervals to receive the events. Again, based on the type of information being provided, a channel may generate events either rapidly to be sent to millions of subscribers or at a slower pace for fewer subscribers.

When an event is received, the matching module 404 matches the received event to the alerts specifications or rules associated with each registered user of the unified notification platform 100 in order to identify the users who have subscribed to receive alerts/updates associated with the received event. Based on the channel providing the event, only a single user or millions of users may be identified by the matching module 404. For example, if the received event was generated by a messenger service a single user may be identified by the matching module 404 for receiving the event alert whereas if the received event was generated by a sports update service, millions of users may be identified by the matching module 404 to receive alerts associated with the event. In an embodiment, the matching module 404 can execute such matching based on the subscription information 152 in the data store. For example, instead of forwarding all updates regarding a particular stock to the millions of users registered with a financial new service, the matching module 404 enables the financial news service to forward alerts regarding particular events associated with a financial entity to users who specify criteria that are satisfied by the event and who have subscribed to receive those events at a desired frequency and on their chosen device(s).

The alerts generation module 406 applies template(s) to the events to generate event alerts. The templates can be applied to generate a plurality of alerts for a given event. For example, a received event may need to be forwarded to a plurality of clients such as, HTTP and non-HTTP clients executed on different devices. Accordingly, multiple templates can be applied to a single received event to generate a plurality of alerts to be forwarded to the HTTP and non-HTTP clients being executed on the various devices. In an embodiment, the alerts generation module 406 can further specify service level requirements such as that the generated alert is a best effort delivery or a guaranteed delivery. In an embodiment, the generated alerts can be forwarded to the delivery module 106 for further transmission to the user. In an embodiment, the generated alerts are buffered upon generation. The buffer 410 is accessed by the delivery module 106 in order to push the event alerts 454 to the users. The alert generation module 406 can be further configured to set a message state indicating the status of the message as new, acted or deleted which facilitates the delivery module 106 to identify messages from the buffer that are to be pushed to the subscribers.

FIG. 5 shows a schematic diagram of the delivery module 106 in accordance with one embodiment. The delivery module 106 receives event alerts 454 and generates corresponding messages 554 to be pushed to the subscribers. In an embodiment, the delivery module 106 comprises an alerts receiving module 502, a channel module 504 and a message transmission module 506. The alerts receiving module 502 accesses the buffered event alerts 454 generated by the alerts module 104. The channel module 504 identifies the appropriate channel associated with each of the received alerts 454 and publishes them to the appropriate channels. In an embodiment, a channel can have associated channel metadata 552 that specifies message transmission criteria such as retention policy, expiration policy, delivery policy, throttle policy and an authorization model for example, OAuth 2.0. The message transmission module 506 transmits the alerts 454 to the user devices 110, 112 and/or 114 through one or more of the plurality of user agents 562, 564, 566, 568 and 572 in accordance with the channel metadata and user specified criteria. Each of the user agents is in turn configured to interact with the corresponding push services such as APNS Apple Notification Services, email service, SMS service, messenger services and HTTP push services such as CometD per well-defined protocol such as for example Bayeux protocol. The delivery module 106 is thus configured to interact with the plurality of push services to provide event alerts via various modalities. In an embodiment, messages can be transmitted to HTTP clients via long-live HTTP connections. The delivery module 106 can be further configured to leverage the plurality of user agents 562-572 in order to efficiently deliver the alerts 454. For example, if it is determined that one of the messages 554 with a guaranteed delivery service specification cannot be delivered via a preferred one of the user agents 562-572 an alternate one of the user agents 562-572 can be identified by the delivery module 106 to deliver the alert. In an embodiment, if a channel associated with one of the received alerts does not exist, the channel module 504 can be configured to create a channel for the message(s). In an embodiment, each of the user devices 110, 112 and 114 maintains a single HTTP/TCP connection with the unified notification module 100 to receive one or more of the alerts 454.

FIG. 6 shows a flowchart 600 that details a method implemented by the subscription module 102 for receiving subscription from a user to receive messages from the unified notification module 100. The method begins at 602 with receiving a user request for registration. At 604, a user interface 254 associated with the unified notification module 100 is provided to the user for selection of the various channels 140 and associated criteria in accordance with embodiments described herein. The user interface 254 thus facilitates as a single registration point for multiple channels providing public and private data to the users. Thus, based on the channel selected by the user, the user interface 254 may alter to show associated options for user selection. At 606 user selections from the channels 140 and their associated options are received and recorded in the data store 120 at 608. The options thus stored are used to recognize events relevant to the user and generate appropriate alerts for transmitted to the user. In an embodiment, based on the received options, new channels can be created in accordance with embodiments described herein. For example, when a user subscribes to receive private information for services such as email, IM, chat or SMS a channel with appropriate authentication procedures can be created.

FIG. 7 is a flowchart 700 that shows details of a method of generating alerts in accordance with one embodiment. The method begins at 702 with the alerts module 104 receiving an event from one of the channels 140. It may be appreciated that the events can be generated by public data sources such as new update channels or other users of the channels 140 such as but not limited to email/IM/SMS/Chat users. At 704, the received event is matched to the rules in the data store 120 in order to identify subscribers who registered to receive updates regarding the received event. If the event is associated with a public data source such as a new service, sports, financial or weather updates, millions of users can be identified at step 704 for forwarding alerts reporting the received event. If the received event is associated with private information source such as an email addressed to a single recipient or an instant message or a message associated with SMS, only one user is identified at 704 for receiving alerts generated from the received event. At 706, one or more alerts for the received event are generated in accordance with options specified by the user(s). In an embodiment, a new alert specification can be generated for one or more channels based on the options selected by the user at the time of registration. The event alerts or messages at 706 are generated based on the specifications. Thus, two users can receive two different alerts related to the same event. For example, if the received event is associated with a public data source, an alert associated with the received event for transmission via SMS to a first subset of the subscribers can be generated at 706. However, another alert for transmission via another modality, for example, email, may also be generated at 706 for transmission to a second subset of subscribers. At 708, the alerts thus generated are buffered for further access by the delivery module 106.

FIG. 8 is a flowchart 800 detailing a method of delivering event alerts corresponding to the event alerts in accordance with one embodiment. At 802 the buffer 410 is accessed by the delivery module 106 to retrieve the event alerts 454. At 804 the various channels associated with the retrieved alerts are identified. Each alert has associated therewith a channel, however, as multiple alerts can be created from a single event, two or more alerts can be associated with one channel. Based on the type of event alerts being published to the channel a single channel can have only one subscriber or it may have millions of subscribers. For example, channels to which private event alerts such as IMs, SMS or mail counters are published can have only one subscriber whereas channels to which public event alerts such as sports scores or new updates are published can have numerous subscribers. Based on the type of event alerts retrieved at 802 various channels for event alert publication are identified at 804. As described herein, a channel which can be identified by a name and serves as a source and/or destination for event alerts. At 806 the event alerts are published to the various channels associated therewith. In an embodiment, event alerts of different formats can be published to one channel as a single event from one of the channels 140 can result in generation of multiple event alerts by the alerts module 102. Based at least on on the channel metadata it is determined at 808 if any authentication is required prior to transmitting the event alerts to the users. For example, channels associated with public data such as news updates or sports news may not require authentication whereas channels to which private data such as emails, IMs or SMS information is published require user authentication. Hence, if different event alerts are published to a variety of channels at 806, a first subset of the channels may require user authentication whereas a second subset of the channels may not require any user authentication. Based on such determination at 808, event alerts on channels not requiring user authentication are transmitted directly at 814. As event alerts may have different formats different mechanisms for transmission such as but not limited to the plurality of push services such as APNS Apple Notification Services 562, email service 564, SMS service 566, messenger services 568 and HTTP push services 572 such as CometD can be employed by the delivery module 106 per well-defined protocol for an event alert delivery at 814. If it is determined at 808 that user authentication is necessary prior to event alert transmission, the delivery module 106 further determines at 810 if each subscriber receiving event alerts on the secure channel is authorized to receive the event alerts. If the subscriber(s) are authorized the event alerts are delivered at 814 in accordance with embodiments described herein. Thus, the delivery module 106 in accordance with embodiments described herein can have built-in steps for authentication so that only authorized subscribers/devices receive the event alerts at 814. If the subscribers are not authorized, the event alert delivery fails as shown at 812. It may be noted that multiple event alerts on different channels can be delivered to a subscriber at 814 via a single connection maintained by the device associated with the subscriber with the unified notification module 100.

FIG. 9 shows data flow in a communication session between a HTTP client on a user device 112 and the unified notification module 100 in accordance with one embodiment. At 902 and 904 a mail channel is initially registered with the universal notification module 100 including the alerts module 104 and delivery module 106 to provide mail alerts to subscribers. When a user device, for example, the user device 112 initially connects 906 to the universal notification module 100, a request 908 can be made to the HTTP push service to provide alerts for the user Bob's mail counter. The HTTP push service 952 forwards the request at 910 to the delivery module 106. Based on the channel metadata, the delivery module 106 implements an authentication model to determine if the user ‘Bob’/user device 112 is authorized to receive the mail counter alerts for the mail channel associated with the user ‘Bob’ at 912. It the user device 112/the user ‘Bob’ is authorized, the delivery module 106 accesses 914 the mail alerts data which may have been buffered at 916 by the alerts module 104 when events were emitted by the mail service 950. Accordingly, the cached data is retrieved 918 by the delivery module 106 and the mail counter information is received 920 by the delivery module 106 which in turn forwards 922 it to the user device 112 in accordance with user-specified criteria. In an embodiment, the connection that was initially established at 906 can be used to forward 928 an alert message the HTTP push service to the user. The alert message can be associated with an event 954 occurring with one of the channels 140 other than the mail service 950. Accordingly, the alerts module 104 generates and forwards 924 an alert to the delivery module 104 which in turn transmits 926 the corresponding message to the HTTP push service 952. Subsequently, a new mail event 930 is generated and accordingly, a new mail event alert 932 updates the mail counter in the cache. A message indicating the new mail counter is transmitted to the user at 938 via the HTTP push service 952 as shown at 936 using the HTTP connection established at 902.

FIG. 10 shows data flow in a communication session between a non-HTTP client on a user device 112 and the unified notification module 100 in accordance with one embodiment. Similar data flow as shown in FIG. 9 occurs, however, it may be noted that no initial action as shown at 902 from the user device 112 occurs. Rather the user Bob is authorized at 1002 to receive alerts and accordingly, the mail counter 1004 comprised in the cached data is forwarded to Bob. In an embodiment, the delivery module 106 can determine that Bob is available via his user device 112 which may be an iPhone and hence the mail counter 1004 is forwarded via the native APNS (Apple Notification Services). Similarly, an alert 1008 associated with an event 1006 from one of the channels 140, other than the mail service 950 and an alert 1010 regarding update 1012 at the mail counter is forwarded to Bob when a mail event 1014 is emitted by the channels 140.
